2D to 2D Transformation (topview)

Dear All,

For a long time I have been working on a tracking project. The last step of my project is to move a synthetic camera top of the domain(a room) and get pixel coordinates of top view the objects.

For this reason, I have used simple OpenGL programming in order to reverse transformation(gluLookAt()&gluUnProject() classes) Unfortunately the position of the real world camera is indefinite. Thus issue is so complex. Until now, I couldn’t achieve to create top view of the domain picture (640x480 Pixels, top-left corner is origin). Maybe you can help me about this dilemma.

Thank you in advance.

Kind regards,


This is speacial tracking application. I have already X-Y pixel coordinates numeric databank(side view) and want to transform these data into top view.
Thank you for your help.
